Contaminated Soil Applications

The contamination of soils as a result of prior chemical production can often be unpredictable and diverse. The majority of such pollutants will require an ex-situ treatment method. Many of our VacuDry units can be used for direct-feeding contaminated soils. To reduce the input amount for thermal treatment, the VacuDry units can also be used in combination with soil-washing plants: In this case, customers only feed the high polluted fractions and screened fines (e.g. below 10 mm), as well as the filter-cake from the soil washing process. However, we are able to handle soil contaminated with mercury, hydrocarbons, PAH, PCB, dioxins, furans, organic-lead compounds and many more. VacuDry plants for on-site ex-situ remediation projects are delivered in a modular design.

Contaminated soil and building-rubble can be efficiently treated with VacuDrytechnology, including a diverse range of toxic and hazardous substances. VacuDryunits also have low emissions and low power consumption, making on-site treatment with our mobile units both economically and environmentally sound.

Helping others clean up the earth by clearing up brownfield remediation odors. Helping others clean up the earth by clearing up brownfield remediation odors. Brownfield remediation consists of removing large amounts of soil that have been saturated with tar, oil or other contaminating substances. Not only dangerous to handle, the disturbed soil is often infused with very unpleasant and in some cases potentially nauseous odors.

The Series 8900 Naphthalene Analyzer provides direct measurement of Naphthalene in ambient air. This instrument is utilized in industrial plants to monitor workplace exposure limits and at remediation and Superfund sites. The Series 8900 Naphthalene Analyzer employs a photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is carried to the pre-cut column. Backflush is timed so that only the Naphthalene and other similar components are eluted to the analytical column. Contaminants on the pre-cut column are backflushed to vent. Naphthalene is separated from potentially interfering components on the analytical column and elute to the detector for analysis.

Historically, landfills have been the most common method of organized waste disposal and remain so in many places around the world. Landfills are essential applications to ensure long service life and prevent soil pollution. In industrial basins, TenCate protection geotextiles guarantee the protection of the geomembrane against all risks of mechanical damages. A cost effective and environmental friendly solution to sort, treat and recycle waste.

The mist eliminator prevents oil mist from contaminating air or soil, helping facilities to comply with environmental regulations. It also makes for a cleaner safer work environment by eliminating oil residue built-up on engine room floors, enclosure and stairwells, while improving indoor/outdoor air quality and reducing fire hazards.

Being able to trust your instruments to make quick, easy and accurate measurements in the field is key when dealing with regulatory requirements. The InfraCal2 infrared analyzer is the choice of experts for measuring oil in produced water; oil contamination in soil; and fats oil and greases in waste streams.

The treatment processes in recycling plants generate unpleasant and often harmful dust, which is a health hazard not only for nearby residents, but particularly for the employees. More and more legislation is being passed on dust control requiring such in the form of mobile units or fixed installations. In composting processes, the dust problem is compounded by unpleasant odors, which can be controlled effectively with specialized equipment. The same units are also used in biogas plants or for the removal and disposal of contaminated soil from industrial sites.

Fugitive emissions can be a health concern during removal and disposal of mercury-contaminated material at remediation sites. Thus, remediation projects either indoors or outdoors often require on-site, real-time mercury air monitoring with a Tekran2537. This assures permitted levels are not exceeded during waste processing and human exposure levels are below government regulated toxicity thresholds. Often multiple sites must be monitored continuously.The Tekran1115 Multi-Port Sampleris the ideal tool for multiplexing the Tekran2537 for real-time continuous on-site monitoring of mercury fugitive emissions.

Several industries and industrial processes may contribute to soil and groundwater contamination. AdEdge Technologies has supplied filtration equipment for several remediation efforts to remove arsenic, lead, and other inorganic contaminants to meet state and federal mandates.

Filter beds with pre-filter are simple, efficient and environmentally friendly ways of treating domestic wastewater from detached houses and holiday homes. The requirements related to operation and maintenance are few in relation to traditional compact plants. These systems can also be adapted to suit clusters of houses, schools, kindergartens, small companies etc.

Sitelab's UVF-3100D is used to test soil to help investigate and clean up sites contaminated by above ground or underground storage tanks (USTs). Soils can be analyzed for extended diesel range organics (EDRO) or extractable petroleum hydrocarbons (EPH). Results correlate well to confirmatory lab methods.

Posi-Shell erosion control coatings are the perfect low-cost solution to protect and stabilize slopes. Our long-term coatings are spray-applied and allow engineers or operators to protect acres (hectares) of slope in a single day. The finished coating is durable and textured, reducing water energy across large areas. The final product eliminates erosion, siltation, and (as a result) expensive rework. The product can be designed to last for years and is easily tracked into slopes when intermediate protection is no longer necessary. Indeed, when integrated, Posi-Shell actually improves soil quality by conditioning it for future seeding.
Posi-Shell’s simplicity and durability make it tremendously effective at controlling windblown dust, infiltration, or runoff associated with clean or contaminated stockpiles. Unlike cumbersome tarps or geo-membranes, Posi-Shell erosion control coatings are spray applied and do not require any ballast. Posi-Shell conforms and adheres to any topography and delivers 100% clean runoff. Stockpile loading or removal is accomplished by breaking into the coating where desired. Active areas may be left open or quickly resealed if required. Posi-Shell erosion control coatings are ideal for protecting expensive piles of salt, coal, or cement clinker; and are used extensively for containing hazardous or radioactive soils.

GPR and EM play an integral part by providing a non-intrusive means of examining the subsurface for environmental hazards such as soil contamination, underground storage tanks and drums. GPR can delineate landfills and pathways for contaminant flow, as well as conduct hydrogeologic investigations such as water table mapping. We offer innovative technology to support site assessment needs.
